A new TV20 EHT stick arrived today and it definitely does not rattle. I wonder if I damaged the old one with too much heat while soldering a thick piece of wire to it. Anyhow, I'm going to make a clip for the new one so I don't have to solder on it at all
.
Meanwhile the overwind is gently cooking at 30°C at 85mA, which should be just under 1W. Hopefully this will be enough.
Over the weekend I'll re-pot the LOPT but before I do I wonder if should do anything to insulate that soldered joint at the business end of the overwind? When assembled it will be around a 1/4" from the inside of the metal can? Obviously it's been like that from new, unless it was painted with something that's subsequently dissolved? Any advice greatly appreciated
.
